Application filed January 26, 1925 Serial No. 4,877,

This invention relates to iu'iprovements in sectional clamps tor cablesand is more particularly adapted to a detacluible connection tor use inconjunction with the cables or wires of a lightning atrrester such as isembodied in my copending application.

Uneo-t the important objects ol the present invention is to provideadetachable connection which is of such construction as to enable thesame to be readily assembled or disassembled thesimplicity thereofenabling considerable time and labor to be saved in its use. i i

it further object is to provide a detachable connection of the abovementioned character, which will at all tin'ies be positive andellic-ient in carrying out the purposes for which it is designated, thesame being further simple in construction, inexpensive, strong anddurable and further well adapted :tor the purposes for Wl'llOli it isdesignated.

@ther objects and advantagesof this in vention Will become apparentduring the course oi the following description.

Th the accompanying drawings liorn'iing a part of this specification,and in which like ntunerals designate like parts throughout the same:

ll igure l is a side elevation oi the detachable connection associatedwith the adjacent ends of the elongated vertically extending wire andthe ground wire.

Figures 2 and 3 are elevational views of the sections oi? said lastmentioned connection, and

lBigure 4t is a. detail perspective view of the wire securing meansassociated with said dotachable connection.

ed at at. A pair oi? cooperating channels 5 and 6 are arrangedin theinner opposed faces oi the complementary sections 2 and 3 the sameextending from the lower end to one side ottthc intermediate portion ofthe connection. for receiving the upper end i of the ground wire A.

A. similar pair of cooperating channels 7 and 8. are arranged 1n theupper portions of the inner faces oi the complementary sections, theconstruction thereof being clearlyillustrated in Figures 2 and 3. Thecooperating grooves 7 and 8 respectively provide an opening forreceiving the lower end of the wire B which extends downwardly along theouter wall of the chimney. l

The lower end of the inner section 2, is provided with the laterallyextending ears 9, the same being provided with internally threadedopenings 10 for registry with the openings 1.1 provided in the laterallyextending cars 12 formed on the lower end of the complementary outersection 3 whereby the fastening screws 13 afford a means for scour-- ingthe lower ends of the complementary sections together. The upperend ofthe inner section 2 is provided with a pair of hitorally extending cars14, the latter being provided with the openings 15 for receiving thetongues 16 formed on the upper end'oi? the outer section 3 whereby aninterlocking and interfitting connection betwecn the up per ends oi thecomplementary sections is provided.

For the purpose of securing the portions of the wires which are disposedin the intermediate portions of the sections of the connection 1, Iprovide the wire engaging member 17 which is removably disposed in theopening 18 provided thereiorin the'intermediate poltion of the outersection '3, the opening "18 being arranged diagonally and communicatingwith the cooperating channels of the section. This wire engaging membercomprises a substantially bloclolike body 2 that is of such size to {itwithin the opening 18 formed in the outer section 3. A plate-like memberis formed on the upper or outer face of this block and is of greatersize than the block, and. the inner face of this plate like portion willengage the outer .l'ace of the outer section around the opening 18. Thebottom face of the rectangular block 24 is cut away at each end asillustrated at 26 and a transversely extending teeth 27 is formed ineach of the cut away portion s. These teeth bite into the ends ()it therespective wires or cable that are arranged in the cooperating channelsprovided therefor in the inner opposed faces of the sections of theconnection. An enlarged opening 28 extends centrally through IOUtachable connection 1 is adapted to be supported in a rigid positionadjacent the chimney through the medium of a bracket 21.

This bracket comprises the complementary sections 22 and 23 which aredetachably secured together by a tongue and slot connection29 atone endand by a screw 30 at the other end.v The bracket is secured on theoutside'of the chimney so that the inner sectionwillybe disposed betweenthe chimney .and the inner section of the detachable'connectionembodying my invention, and the outer section of this bracketcnc-irclesthe upperouter sect on of the connection as vclearly illustrated inFigure 1. This bracket a is adapted-to be supported on the chimney inany appropriate manner.

It will thus be seen from the foregoing description,-, that detachableconnecting means-has been provided for use in connection with thewiresorcables of the lightning arrester'system embodied in my copendingapplication .whereby' the several wires or cables may be readilyconnected or disconnected without the loss of any considerable length oftime or labon Furthermore, the provision of connecting means of theabove mentioned character, will :obviate the necessity of having tosplice the wires or otherwlse prov de a permanent connectiontherebetween. The simplicity in which my various detachable connectionsare constructed will enable the same to be readily and easily vadjust edand-furthermore will prevent any possibility of the displacement of thewires I I claim is 1. A device of the class described comprising aconnection including a pair of complementary sections, said sectionsbeing provided with cooperating channels for receiving the end portionsof a pair of cables, the intermediate portion of one of said sectionsbeing provided with an opening which communicates with the channelsformed in said sections, a member adapted to be disposed within theopening for securing the free ends of the cables in said connection, andmeans for detachably securing the sections together.

2. A device 01 the class described comprising a connection including apair of complementary sections, said sections being provided withcooperating channels adapted to receive the end portions of a pair ofcables, the intermediate portion of one of said sections being providedwith an o )cning which communicates with the channe s formed in saidsection, a block adapted to be secured in said' opening, said blockbeing provided with channels adapted for cooperation with the adjacentportion of the channels in the other sections for securing the free endsof the cables in said sections, and means for detachably securing saidcomplementary sections together.

In testimony whereof I afiix my signature.

HENRY HEESE.
